Oil Pressure Regulator - Street 80-85 PSI

Oil Pressure Regulator - Street 80-85 PSI

The Racing Beat high performance Rear Oil Pressure Regulator is designed for use on all 1971-1992 12A, 13B, and 20B engines and interchanges exactly with the stock unit. As supplied by Mazda, the factory pressure regulator is intended to bypass at maximum nominal rate of 71.1 PSI. For use on higher performance street applications the Racing Beat regulator can be substituted, which bypasses at a higher maximum nominal rate of 80-85 PSI.

As a general rule, oil pressure should be increased as the horsepower output and engine RPM increases. As horsepower and RPM demands increase, it is beneficial to have higher oil pressure between the shafts and bearings to prevent possible catastrophic contact between spinning components. Additionally, as oil pressure is increased, flow rate also increases - hence, more oil is available to cool the bearings and rotors.

Tech Notes:

- The 1993-95 13B Twin Turbo the factory rear oil pressure regulator bypasses at a maximum nominal rate of 110 PSI. For more information on how to increase oil pressure for this application visit our Oil Tech Tips section.

- The 2009-2011 RX-8 Renesis engine is not equipped with a rear pressure regulator. Nominal oil maximum oil pressure on this application is 110-115 PSI. We do ot offer a regulator to increase the oil pressure on this application.
